Abstract: An exchanger for a tank is described herein. The exchanger may be relied upon in a trailer tank, for example, or any other type of tank that stores fluid. The exchanger includes an inlet, a central fluid conduit, one or more exchanger extension arms having fluid apertures that direct fluid into a tank at various locations, and one or more supports that support the central fluid conduit and the exchanger extension arms. The fluid apertures may be positioned relatively evenly across the exchanger extension arms and/or the central conduit to direct fluid up or at various directions into the tank. Thus, fluid pumped into the inlet of the exchanger may flow through the central conduit, into the exchanger extension arms, and out through the fluid apertures at various locations into the tank. As such, heated fluid, for example, may be more evenly and quickly distributed into the tank.

Abstract: The present invention relates to a device for mixing fluids. It is a hydraulic or pneumatic apparatus, depending on the fluid used for transportation. It is static and has the characteristics of both an extractor and a fluid mixer. Extraction is effected by dragging the suction elements, by means of the circulation of a transporting fluid injected at low pressure. The injection inlets (5 or 6) and suction inlets (6 or 5) are interchangeable and lead to a single outlet (3). The injection tube (1) formed by a helical spiral on the outside surrounded by the sheath (4) increases the pressure in the transporting fluid and creates outward helical movement with centrifugal force in all the fluid that circulates on the outside.

Thus, the stop plate of the stop member prevents the air in the air cushion from leaking outward through the vent holes of the connecting member, so that the air tap assembly has an anti-reverse effect to prevent the air from leaking outward from the air cushion during the inflating process, thereby facilitating a user inflating the air cushion.

Abstract: A diluent passage 12 to introduce special liquid and a rinse liquid supply passage 13 which is separate from the diluent passage 12 are formed in the main body 10, and a plurality of jets are disposed at a cylindrical dial 18. A water convey passage is formed to connect two positions at the rinse liquid supply passage 13 where pressure difference occurs therebetween to the other jets 19b, 19c except the jet 19a through which the special liquid is introduced. When water flows in the rinse liquid supply passage 13, the water is introduced to the water convey passage due to the pressure difference of the rinse liquid supply passage 13. The water rinses the other jets 19b, 19c except for the jet 19a through which the special liquid is introduced. Therefore, adjusting changes or choking of the jets 19b, 19c which have not been used for a considerable time can be prevented.

Abstract: The mixing state of static mixing is optimized, so that it is possible to form silver halide emulsion particles in small sizes with an excellent mono-dispersion characteristic. An aqueous solution of haloid salt is blown out from a first nozzle into a mixing chamber as a rectilinear flow of turbulent flow, and before eddy viscosity formed when the rectilinear flow is blown out from the first nozzle of a small diameter to the mixing chamber of a greater diameter reaches a maximum, or before a maximum flow speed of the rectilinear flow is reduced to {fraction (1/10)} or below, an aqueous solution of silver nitrate is blown out from a second nozzle as a crossflow of turbulent flow which crosses the rectilinear flow at a substantially right angle and is entrained by the rectilinear flow, so that the two solutions are allowed to mix and react with each other instantaneously, and a liquid resulting from the mixing and reaction is discharged from a discharge duct.

In an alternative embodiment, a chemical staging recession is structured on an outer aspect of the body. The staging recession forms a reservoir for fluid chemical when the insert is positioned within a chemical injector.

Abstract: An apparatus for inserting a venturi tube having an inlet, an aspirator inlet and an outlet directly within a fluid flow stream, with the aspirator inlet not in contact with the fluid flow stream is disclosed. A plate having a first aperture leading to the venturi inlet, and a series of second apertures both supports the venturi within a conduit and divides the fluid flow stream into a first stream which flows through the venturi tube and a second stream which flows around the venturi tube. A variety of adjusting mechanisms are disclosed for varying the cross sectional area of the second apertures relative to the cross sectional area of the venturi tube. The apparatus is adapted to allow the back pressure within the venturi tube (which increases as the fluid flow rate increases) to force an increasing proportion of the flow stream to flow around the venturi tube in order to maintain a relatively constant aspiration rate within the venturi tube.

Abstract: A cleaning chemical dispenser is provided. The dispenser includes bowl assemblies accommodating inverted containers with solid cast cleaning chemicals. The chemical dispenser generates cleaning chemical solutions by spraying a solvent such as water onto the solid cast concentrates. Concentrates from two of the containers are blended together, but are kept separate from the concentrate from the other container. All concentrate solutions are then further diluted in a venturi containing separate paths for each of the blended and separate solutions. The diluted solutions are then separately routed to the use container.

Abstract: A foaming system 10 includes a dual aspirator 13. The dual aspirator 13 has first and second aspirators 80 and 81 to pick up a first and second chemical concentrate. The diluent first chemical mixture is drawn in through the first aspirator 80 and goes through a first diffuser 46 where the first chemical/diluent mixture is further mixed. Similarly, diluent/chemical mixture is drawn by the second aspirator 81 and flows through a second diffuser 47 where it also is mixed. The two diluent/chemical mixtures then combine after exiting the diffusers and the compatible chemicals are then mixed by the flow of the diluent/chemical mixtures. Flushing lines 68 and 71 provide for cleaning of the dual aspirator 13. Further, the diffusers have a ratio of their diameter to length to aid in the prevention of contamination along with the use of two check valves 48 and 49.

The injection tubes of each pair extend in radial directions from, and in the same plane normal to, the axis of the tubular injector body. Moreover, all injection tubes are in one of two planes coincident to the axis of the tubular body and all pass through a plane parallel to the axis of the injector body.

Abstract: One non-propelled fluid resident in a reservoir is sucked into the flow path of a further fluid in transit propelled by fluid pressure. This is achieved by means of inducing a spiral cyclone path flow pattern in the propelled fluid to create a converging vortex with a turbulent mixing zone into a linear output transit line. The pressure at the vortex zone is reduced significantly from atmospheric to thereby produce a strong suction propellant force bringing the stored fluid into the turbulence mixing zone. The stored fluid is introduced axially in line with the cyclone axis and linear output transit line which receives thoroughly mixed fluids in substantially constant proportions over significant changes in pressure of the propelled fluid. Thus, the mixer device is ideal for dispensing insectides with a garden hose, detergents into a dishwasher, chlorine into a swimming pool, etc.
